Statistical quantification of atomic-resolution HAADF images, as well as numerical simulations, are employed to interpret the contrast from Bi-containing columns at atomically abrupt (001) GaAs-GaAsBi interface and the onset of CuPt-type ordering. Using monochromated EELS mapping, bulk plasmon energy ...
The combination of ASCOR with a Cold-FEG allows for higher resolutions to be achieved, 0.071nm in HAADF-STEM, with unprecedented game changing resolution at lower voltages. Automated aberration correction software JEOL COSMO™ (Corrector System Module) JEOL’s COSMO™ software module utilizes a ...
The recorded data allows to investigate the effect of inelastic scattering on sub-unit-cell length-scale. To this end, the atomic column positions are found in the HAADF images and for each pixel in the image, the distance to the nearest atomic column is calculated in units of the average ...
atoms and C atoms was 1.6, which matched the∼Z1.7dependence of the HAADF contrast on the atomic numberZof O (Z = 8) and C (Z = 6)36. The oxygen-containing function groups on graphene membranes not only improved their hydrophilicity, but also can efficiently anchor and stabili...
While the advent of high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) provides much more information at the atomic-scale, there is still a need for performing atomic-resolution chemical mapping using advanced STEM techniques, such as energy-dispersive X-ray ...
Atomic resolution STEM-HAADF/ABF images and EDS maps for GaN[211]Feature2 New enclosure The TEM column is covered by a box-type enclosure, which can reduce the effect of environmental changes such as temperature, air flow, acoustic noise and so on, and then it improves the stability of ...
In this article, the interface structure and strain of the Bi2Sr2CuO6+未Bi-2201)/MgO superconducting heterojunction prepared by molecular beam epitaxy were investigated by aberration-corrected high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM), energy-dispersive X-ray ...
In the present work, an atomic scale energy dispersive X-ray spectroscopy (EDS) mapping study with the aid of HAADF STEM has been conducted to determine the distributions of component atoms and to examine the effects of Cu on η precipitates in an Al-Zn-Mg-Cu aluminium alloy. The components...
1d that non-idealities in the imaging, such as slight local sample or beam tilt, have a much larger deleterious effect on the image than in an HAADF image; in this image, the imaging is almost perfect at the top, but there are more streaks and imaging artefacts in the lower part ...
